To all whom t may concern.' a

Be it known that I, EDWIN A. OLLnY, of Syracuse, in the county ofl Onondaga, in the State of New York, have invented a certain.

'and the invention consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had tolthe accompanying drawing in which designate corresponding parts in all the views. I.

Figure 1 is an elevation of this -outlet box and means for coupling the same to the oontiguous sections of' electric conduit.

-Fig. 2 is a longitudinal sectional view of parts seen in Fig. 1.

1 is the outlet box. 2 are electric conduit sections to which the outlet" boxes may be secured, such sections inclosing the Wires 3 which have an outlet through the box 1.

The box 1 is provided with an opening in one of its 'longitudinal'sidea and such opening is covered .by a suitable closure 4, usually formed of insulation andhaving openings 5 at its ends for the outlet of the Wires 3, the closure being detachably secured in position'by screws 6 passing through openings in the closure and threading into lugs Son the inner face of the box 1.

The conduit sections 2 are connected to the outlet box by suitable means having clamping membersl movable in a direction axially of the conduit, and in the illustrated embodiment of my invention the box is provided with externally threaded nipples 9 usually arranged at the opposite ends of the Eox and in axial alinement, said nipples 9 ein in ahnement with the con uit sections 2, so

l that the end faces of the nipples 9 and the from each other.

Valined parts 2, 9 is preferably of larger disections 2 are opposed to and spaced apart Qne of each pair of the ameter than the other, and a detachable cupshaped member having an opening in its bottom is threaded on the part of less diameter, the bottom forming a peripheral shouladapted to be brought vinto position der on "such part of less diameter, and said parts are coupled together by a second memer as a sleeve threading on the part of larger diameter and having an inturned flange coacting with the. ring during the turnino of the sleeve into operative position.

In e illustrated embodiment. of my in' vention each nipple 9 is of larger diameter than the conduit section 2 to which it is i coupled, and a .ring 10 .threads onto the threaded endof each conduit section 2 forming-the peripheral shoulder, the ring10 being also formed with an inturned flange 11 vwhich is interposed between the opposing end faces of the contiguous nipple 9 and the corresponding conduit section 2 the,internal faces of the nipple 9, int-urned flange 11 and conduit 2 being substantially flush;

and a coupling sleeve 12 threads on each nipple 9 and is provided with an inturned annular ange 13 at one end which engages the contiguous ring 10`during the turning of the sleeve onto the nipple 9 and tightly couples the nipple to the corresponding conduit section 2. In furnishing the boxes to the trade the coupling sleeves are supplied therewith and the sleeves are threaded on the nipples, and the rings for turning on Patented May2e, ien.

relative `positions of the conduit or the box.

What I claim is:

The combination of an electric conduit having an externally threaded end, an outletA box having an integral nipple externally threaded and of greater diameter than the conduit', `said conduit and nipple having bores of. substantially` the same diameter, a cup-shaped member having an opening through the bottom thereof of approximately the diameter ot said bores, the vouter face of the bottom 'of said member abutting against the end of the nipple, the inner face of the bottom of said member abutting against the end of the-conduit, and the inner peripheral wall of the member beingl threaded for engagement with the external threads of the condault, and a second member internally threaded for engagingthethreads of the nipple and provided at' its outer end testingwitnesses, at Syracuse, in the county s with :i lzmge,' the inner face of which abuts of Onondaga, in the State of New York, this against the edge of the first-named member 18th day of May 1911,
